8.2 Door Check Switches
When the LED of the [U READY] or the [L READY] button is ON, the
door on the pertinent side is electromagnetically locked, making it
impossible to open.
When the LED of the [U READY] or the [L READY] button is OFF,
the electromagnetic lock of the door on the pertinent side is un-
locked.
When a magazine is separated from the elevator shaft, the
power to the elevator shaft is kept supplied because danger
decreases.
